That's actually an interesting question... I've never seen a site that bothered to post the typical lifespan of hermit crabs.
I can tell you that I've had my dwarf zebras for a year and a half now, and with no indications that they are likely to die of old age any time soon.

http://en.wikipedia....iki/Hermit_crabHermit crabs are often seen as a "throwaway pet" that would live only a few months, but species such as Coenobita clypeatus have a 23 year lifespan if properly treated,[21] and some have lived longer than 32 years.[22][23]
